HENRY TURNER, OF CHARLESTOWN, NEW HAMPSHIRE.

BOX non JOURNALS.

Specification of Letters Patent No. 8,915, dated. April 27, 1852.

To all whom it may concern: l

Be it known that I, HENRY TURNER, of Gharlestown, Sullivan county, andState of New Hampshire, have invented new and useful Improvements in.Boxesfor Railroad- Cars, and that the following is a full, clear, andexact description thereof, reference being had to the accompanyingdrawings, making part of this specification, in which Figure 1, is alongitudinalsection. F 1g. 2, a cross section at A, a, Fig. l, and Fig.3, a perspective view of the lining of the inside bearing.

The same letters indicate like parts in all the figures.

My invention has reference to the construction of the cap box in whichthejournal bears, with the view to give it the requisite strength and atthe same time prevent friction and overheating. With this view I makethe cap box of cast or malleable iron in the following way: I take twoor more fiat square rods of wrought iron and coat them by casting onthem gun metal; these are placed in the sand mold diagonally and themold formed to cast the box thereon, so that when molded they projectout of the cast iron. The space between them is then filled up with softmetal; the said rods of wrought iron are placed in the mold in adiagonal position with reference to the length of the box and curved tocorrespond with the semicircular form of its cross section.

In the accompanying drawings a represents a cast iron box which may beof the usual or any desired form; the inner face f,

of this box, in which is made the opening through which the journale,enters, is composed of a double plate of metal in which I place twoleather washers 6,6, each provided with an opening for the journal 6,concentric or nearly so with the opening in the plate; each of thesewashers is provided with a spring a, of any desired form of means ofwhich one of thewashers is kept constantly bearing down on the journaland the other up to it, thus keeping the whole circumference around theournal constantly closed which effectually prevents the escape cal ballor knob h, on the inside, against which the cap box 2', which has acorrespond'ing recess in its bottom, rests, by

means of whichthe. cap box is enabled to yield to the motion of thejournal due to inequalities in the road, thereby preventing strain,friction and consequent overheating.

The cap box i, is made of cast or malleable iron and has two or morefiat square rods 70, of wrought iron placed in a helical position in thecylindrical cavity of the box, and which have been previously coatedwith gun or other hard metal. The spaces between them are filled withsoft metal Z or composition. By means of this combination and arrangement the wroughtand gun metal sustain the weight, and keep the softmetal in place (except that a thin film spreads itself over the hardmetal surface), and the iron pieces being in a diagonal position, they,together with the semicircular end pieces a, of the cap box retain thesoft metal or composition in place. In View also of the diagonalposition of the hard metal pieces it follows that they act on thejournal in the line of a helix, and that consequently there is little orno tendency to cut or injure the journal.

It is obvious that it is not indispensable to make the inner face of thebox of a double plate, as the object is simplyto sustain the leatherwashers in their proper posit-ions, the same thing is obtainable byother means; nor do I desire to limit myself to leather, as other andperhaps better material may be found applicable.

I claim Making the cap box in the manner described, that is to say ofalternate pieces of hard and soft metal, arranged in a helical position,by which, together with the circu lar end pieces the soft metal iskeptin place, and friction and injury to the axle pre vented, substantiallyas described.

HENRY TURNER.
